Johan Oviedo has thrown 2,914 pitches that have been tracked by the PITCHf/x system between 2020 and 2023, including pitches thrown in the MLB Regular Season and Spring Training. In 2023, they have relied primarily on their Slider (87mph) and Fourseam Fastball (96mph), also mixing in a Curve (80mph). He also rarely throws a Change (87mph).
In 2023, compared to other RHP:
Their slider results in more flyballs compared to other pitchers' sliders, is much harder than usual and has some two-plane movement. Their fourseam fastball has heavy sinking action, is basically never swung at and missed compared to other pitchers' fourseamers, results in many more groundballs compared to other pitchers' fourseamers and has well above average velo. Their curve generates an extremely high number of swings & misses compared to other pitchers' curves, has little depth, is slightly harder than usual and results in somewhat more flyballs compared to other pitchers' curves. Their change (take this with a grain of salt because they've only thrown 6 of them in 2023) is much firmer than usual, results in more flyballs compared to other pitchers' changeups, has slight armside fade and has some natural sink to it.
